Based on the App G fan curve, if we have a oversized VAV supply fan, the power usage will be lower than a properly sized fan.
For example, need 5k cfm
a 10k cfm fan operate at 0.5 load, corresponding power is 0.3 of full load based on G3.1.13.15.
a 5k fan will use 100% of its full load power.
And a 10k cfm fan will have full load power twice of the 5k cfm fan since they are sized based on the same pressure drop, the only difference is the cfm. Am I correct or I am missing something?
